Earth Leakage Sensing
Earth leakage breaker current transformers are used for detecting when the current is leaking to the ground. Unintentional earth leakage occurs due to the insulation fault which allows current to leak from the life circuits to earth by the protective conductor. There could be a breakdown in the conductor insulation or moisture ingress among other causes. Leakages to occur due to the imperfections in the insulators which make the component such as semiconductors and capacitors. humans and animals are protected from electrical shocks. Earth leakage sensing device is a device used for electrical attachments with high impedance for the blockage of shocks. It is manufactured by Shah electronics which is the chief producer of ferrite coils and current transformers. There are various applications of earth leakage sensing like overhead protection circuits, Earth leakage circuit breakers, single-phase or three-phase motor overload protection, electro-mechanical safety valves, electrical safety control gear, etc. All in all, Earth leakage circuit breakers are used for detecting small random voltages on metal closures and break the circuit if a dangerous voltage is found.
